Superbly crafted low-budget thriller with more twists and turns than you can shake a stick at, and plenty of ghoulish humour along the way as well.
The cast play it very well, although Richards' self-centered movie director is a bit hard to take at times. The tiny two-scene cameo by Sir Alec Guinness, oozing menace as the crime czar of Moscow, is simply the icing on the cake.
Well worth repeated viewing, but not on dark nights when you're all alone!
